I wish I could agree with Mofimadness about the Olive. I recently had an extended audition at my local dealers in a good system, Krell electronics and Kef Blade speakers. like you, I am computer phobic and wanted the Olive to be the solution for me. Unfortunately even the Olive 6 seemed flat and unenvolving, lacked soundstage depth and dynamics. It was not a patch on the Naim NDX and unitiserve next door and that was about equivelant to my midpriced Leema Antill CD player.
I concluded that I am just going to have to bite the bullet and go for a Mac laptop or mini, with a decent DAC and an IPad. I heard such a system in the home of a nearby enthusiast, who showed me how it all works. It was all crystal clear to me(not)
